Miro ⬆ • RANK: 4

CEO: ANDREY KHUSID VALUATION: $17.5 BILLION DIGITAL COLLABORATION

Miro has come a long way from its roots in Perm, Russia, where CEO Khusid’s father once ran a small printing company and where, frustrated by the challenge of showing work to clients far from the office, he cofounded the digital whiteboard software business in 2011. In January, Miro raised $400 million at a $17.5 billion valuation; now headquartered in San Francisco and Amsterdam, it’s the big mover on this year’s Cloud 100 list, vaulting 32 spots to No. 4 thanks to 39 million users and clients such as Dell, KPMG and Under Armour. But when Russia invaded Ukraine in February, its origin became a liability. Miro’s leaders huddled for 48 hours, then announced the shutdown of their Russian office and ceased sales in the country. “When you have to make very difficult decisions in a very short period of time, nobody has a playbook for that,” says head of operations Grisha Pavlotsky (above).
